without wishing to appear brusque, or rude Rich, there are hundreds of open.l et alone partially protected shafts in this area. and whilst we are interested in access, exploration and a good trip in such we are a small minority of the population. this mine is under private property. the buildings and shaft accesses (plural .) are safe for joe public to walk his dog on nearby footpaths, oblivious of troglodyte pleasures abounding below fido's 'rest stop !'
whilst the timbers are of some age (poss' pre cambrian! ) they'd stop a sheep or pet dog from achieving terminal velocity ,just prior to terminal breath.
Tho' a really good lid would be smashing. and cost a shekel or two,eh (who wants the bill?) i'll tender for the contract in these hard times.
derbyshire leadmines project? pdhms, negotiation, access agreements, controll. the stuff of nightmares.
beyond a 'casual' insured agreement of access.
worries of aforementioned ginging at points down the main shaft.
security of artifacts.
too many casual visitors.
i feel i'm on a hiding to nothing for expanding so, so i'll invite reply.
thanks for fetching the topic to forum. see what comes of it
cheers Rich. O. G.
come on brains i know you'll have a view /valid input.
